http://i.imgur.com/Bpt3J0z.jpg This shows only how to connect the serials between the frsky module and 9x, to allow you having all the telemetry data and configuring options on the 9x LCD. http://www.rcgroups.com/forums/showthread.php?t=1510047 Unlike other methods, this is the most simple, requiring no signal inverting transistors or other electronic components. You must flash an ER9X-FRSKY version, see bellow latest/stable binaries: http://code.google.com/p/er9x/#Latest I cannot be held responsible for any damage occured after doing this mod. Do not mess with SMD stuff unless you have some decent soldering skills and electronics knowledge.
